RED SHADOW AROUND IMAGES of SONY KP-57WS510 RPCRT

My SONY KP-57WS510 RP TV has developed a red and blue shadows around the images. I love my this TV. I tried to adjust the convergence per the manual, but the red crosses does not move even move a micro millimeter. I have used the toggle button to have the red box around the cross to move. It does not move at all. Any kind of help will be highly appreciated.

Thank you in anticipation

    Thank you for your solutions to my problem of red shadow. How many ICs I need to replace. I was about to order one but then thought I rather confirm with you the no. of ICs I should order. Please advise.



    Like you suggested I should order 6 of 4.7 ohm x1/2 watt resistors too but how I would know that they are burned too. Please help.



    Thank you

    Regards

    Check the following url about the specs of stk392-560. It said "
    Use the STK392-570 to repalce the STK392-560". Should I have to buy STK392-570 instead of STK392-560?

Your set uses two STK392-560 convergence ICs they are attached to a large heat sink on the D board. You can save your self about 400 for a twenty minute repair by getting new ICs at the following link as trhey provide free instalation instructions with pics so you can do the job yourself. It only requires basic soldering skills I would order about six 4.7ohm 1/2 watt resistors as well just in case you need them asusually sonys' will burn one or two of the 4.7ohm convergence resistors when the ICs fail. Heres the link

    you will need two of the STK392-560 ICs. As far as the resistors they will often show up as discolored in the middle, But if not its easiest to lift one side of the resistor from circuit and check them with an ohms meter if theyre bad they wont register on the meter. If you dont have a meter Radio shack has them cheap as does the site that I directed you to has the ohm meters as well.

    Plus they will help you through the proveedure to check resistors and even tell you which resistor numbers are likely to be the ones open

The problem is your convergence ics there are two. cost of part is 30.00 you would need a tv repair shop to fix . The cost is around 300.00. total. call around and get quotes fom service centers. T his is a common problem every 3 to 5 years so if you where going to fix it would last 2 to 3 years,


thanks doctor video

Sony rear projection tv shadow images around people red and green blue and purple


I think your TV has beam convergence problem. Depending on the model there may be user adjustments on the TV to align the beams on to the same spot as close as possible so that color shadows are minimized. Strong magnetic fields such as nearby unshielded speakers can also cause this problem. If that is the case, moving such magnetic field sources away may be the only solution.

Panasonic PT-51HX41 rear projection tv showing shadow/double images.


Unplug the TV from the ac wall outlet for about 4 minutes then plug it back in and turn it on. If it still has a double image then tell me if it's affecting the menu screen from the TV (not the cable menu). And is the double image in red and blue?
